I think we are in agreement. If there is a public function to unload, you
can call it. If there isn't, it's a missing feature that cannot be provided
by anyone other than the code's author. it's not possible to safely unload
code as a blackbox without knowing all of its implementation details.
Both gitstatusd and p10k do provide public functions for unloading. You are
welcome to call them. They guarantee that repeated load+unload won't leak
resources. That is, as long as you don't unset any of their internal
variables. They do leave a handful of global parameters after unloading;
without them they cannot be loaded correctly again.
